STATES EDWARD CHARLES PETCHER, OF ST. LOUIS, MISSOURI.

ATOMIZER.

Application filed April 26, 1921.

To all whom it may concern:

Be it known that I, EDWARD C. PnroHER, a citizen of the United Statesresiding at (now) St. Louis and State of Missouri, have invented new anduseful Improvements in Atomizers, of which the following is aspecification.

This invention comprehends the provision of an atomizer, which is verysimple in construction, eliminating the bulkiness and cumbersomearrangement of parts embodied in the atomizers in general use, one thatcan be used for spraying throats, or adapted for perfumes where a fewdrops are necessary, and particularly advantageous for use by tourists,the invention being sanitary due to the fact that the atomizer tube isnormally arranged in the solution.

The chief characteristic of the present invention resides in providing acombined liquid chamber and atomizer tube adapted to be normallyarranged within a bottle or other suitable container for the solution,the tube being equipped with means for drawing in the desired quantityof solution and subsequently discharging the solution from the tube inthe form of a spray, after the tube has been removed fromthe container.

Another object of the invention resides in equipping the combinedchamber and atomizer tube with means for supplying the container withair incident to the removal of the tube from the container, therebyeliminating suction and making it very easy to remove the tube from thecontainer when desired.

The nature and advantages of the invention will be better understoodwhen read in connection with the accompanying drawings, the inventionresiding in the construction. combination, and arrangement of parts asclaimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a vertical sectional view through the atomizer constructedin accordance with my invention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a detail view partly in section of the stopper for thecontainer.

Specification of Letters Patent.

Serial No. 464,617.

Figure 5 is a detail View of the two-part button used in connection withthe air bulb.

Figure 6 is a detail view of the combined chamber and atomizer tuberemoved from the container.

Figure 7 is a plan view of the valve.

Referring to the drawings in detail, 10 indicates the container for theliquid which may be constructed from any suitable material and of anydesired configuration, the container being equipped with a stopper ofthe construction illustrated in Figure 3. This stopper is preferablyconstructed of rubber including a hollow tubular portion 11 and a flange12 which is curved downwardly as at 13 and in its normal positionterminates in close proximity tothe body 11 of the tube. lVhen applyingthe stopper to the container 10 it is necessary to stretch the flangeand its downturned portion over the head at the mouth of the container,and in this manner the stopper is effectively held in position upon thecontainer.

The combined chamber and atomizer tube is illustrated at Figure 6 and ispreferably constructed of glass, although any other non-corrosivematerial may be used. This element comprises a hollow tubular bodyportion 14 which is of uniform diameter throughout its length except forthe tapered extremity 15 which is positioned within the container 10,and the shoulder 16 which reposes upon the stopper 11 when the said tubeis positioned within the container 10 as illustrated in Figure 1. Thetube is provided with alongitudinally disposed air passage or channel 17which opens at both ends of the tube, this channel being arrangedsubstantially at a right angle to the outlet opening 18 at the lower endof the tube for a purpose to be hereinafter described. The interior ofthe tube defines a chamber 19 which merges into a restricted passage 20adjacent the upper end of the tube as shown. The tube projects a slightdistance above the shoulder 16 and is closed and sealed by the cement orthe like 21, a valve retainingelement in the nature of a metallic plate22 being imbedded in the cement and formed to provide a dependingportion 23 which bears against a valve 2% to normally hold the latterseated upon the internal shoulder 25 formed in the tube immediatelyabove the restricted passage 20 thereof. This valve is flexible, beingpreferably constructed of rubber and has its periphery notched as at 26to provide air passages which communicate with an air outlet port 27 atone side of the tube. A 5 float valve 28 operates within the chamber 19so as to prevent the escape of the solution which enters the chamberthrough the port 18.

Carried by the exposed end of the tube 14 is a compressible bulb 29whichcommunicates with the air channel 17 of the tube, this bulb beingprovided with an opening in lthe top which is closed by a two-partbutton, the respective parts being indicated at '30 and 31 respectively.The part 31 which enters the part 30 and is formed with 1 bendableprongs to hold the button associated with the compressible bulb, whilethe part 30 ofthe button is provided with slots 32 which admits air tothe bulb as will be understood. The opening in the top of the bulb isnormally closedby a flap valve 33 which is arranged beside the bulb, thebutton above described being provided to eliminate dirt, dust or otherforeign matter from entering the container 10 through the bulb 29.

The combined chamber and atomizer tube above described enters thecontainer 10 through the stopper 11, during which time a portion of thesolution contained in the bottle enters the tube through the opening 18.If the chamber does not fill with the solution, and you desire more ofthe same within the tube 14, it is only necessary to compress the bulb29 forcing air into the container through the channel 17 thereby forcingthe solution into the tube 14. The float valve rises with the solutionuntil it reaches the position occupied in Figure 1 which closes theupper end of the chamber and prevents the solution from passing throughthe restricted passage and out through the air port 27. When it isdesired to use the atomizer, the tube 14 is supplied with the solutionin a manner just described, after which the combined chamber and tube 14is wholly removed from the container 10. The solution in the tube canthen be discharged through the openlng 18 by compressing the bulb 29 asw1 ll be readilv understood. lVhen the tube is initially inserted intothe solution, the air passes up through the chamber 19 and past thefloat valve in advance of the solution and flexes the valve 24 so thatthis air is permitted to escape through the port 27. When the tube isbeing drawn or removed from the contalner 10, air is forced down throughthe channel 17, to supply the container 10 with the proper quantity ofair in order to eliminate suctlon, and then permit the tube to be easilyremoved from the container when its use is. desired. The inventionprovides thevery handy atomizer, which can be conveni- Y 9 F fly a rnged in. a su tcase or the like, and

eliminates the cumbersome arrangement of the parts as embodied inatomizers of present day use. It is desired to have it understood thatthe combined chamber and tube 14 can be constructed in any suitable sizeto vary its capacity without destroying the general appearance of theatomizer.

VVhileit is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is'herein shown anddescribed, and that Such changes may beresorted to when desired as fallwithin the scope of what is claimed.

What I claim is: p 7

An atomizer comprising a container, a combined chamber and atomizertube normally positioned within the container and adapted to be removedtherefrom for use, said tube having an air channel, a compressible bulbcarried by the tubeand communicating with said container through the airchannel and a valve controlled air escape port for said tube.

2. An atomizer comprising a container, 2.
